Question about Vizio Televison & Video

1 Answer

I have a Vizio M50-C1. Just recently, the screen suddenly showed a bunch of colored lines and disappeared and audio could be heard then even that went away. I power cycled the tv and no luck. The power indicator turn on bright and then slowly fades away. When i push the button again it starts to blink. I counted and it blinks off and on for 15 times. I opened up the tv and nothing on any boards look burnt. I tested the fuse with a multi meter and it showed a .3ohm resistance. I am not sure if it is power/fuse or something else. I see that you have parts but i don't want to but something i do not need. I am hoping you have heard of this before and can provide suggestions?

It could be many things but i would start with the power supply board with the power problem, could just be bad capacitors, which is so common on tv and monitor power supplies.

However, the colored lines could be an even worse sign that the mainboard failed if the power supply output voltages are good.

I would start with checking the voltages from the power supply board, if your lucky the voltages are labeled at one of the connectors. If all the voltages are what they should be, and you don't see any bulged capacitors, then its most likely a failed mainboard. Not much you can do to repair them, just have to find a replacement, which in itself can be difficult!

I just read this for the same problem: push sanitize, then heat and dry, sanitize, heat and dry, sanitize, heat and dry, cancel, then open and close the door. It worked. The dishwasher is running correctly even as I type this.

I suspect for either of these units that the timer control boards are bad.

I had the same problem. blinking 9 times, pausing, 9 times...... remote would not power the tv on. after five minutes of pressing the remote it finally would. after turning it off you would have the same problem. sometimes a half hour of pressing remote in every which what way. finally left the tv on for three days and would mute at nite to go to bed. didn't think that was the best way so turned it off and it never turned back on. checked all the forums and found out it was the g board. unfortunately, you cant buy the whole g board anymore. if you take the back panel off the tv, on the lower left corner is where the g-board is. there are 3 little things to unplug and two screws (phillips head) in the middle of the g board. its simple to figure how to take it out. go to the sony direct parts website. the part # is A1054157A for the g board. since they dont sell it anymore they have a phase 3 program where you send in your old g board and they repair it for 64.95. it'll cost about 8 bucks to ship it to them. better than the 400 bucks the tv guy wanted. address is sony customer satisfaction ctr. , materials door 27H, mount pleasant, PA 15666 there number is 866-748-8272. call first and they give you the step by step instructions what to do. after tax and shipping it came out to less than 80 dollars.even came with a warranty. got it back in a week, popped it in and just love turning the tv on. anyone can do it.

SOURCE: tv wont turn on. power button blinks

if your tv is blinking you are still okay but your set needs service, maybe some board or circut is defective. this happens with panasonics, they have a blink timer. they blink a certain number of times. this blinking feature is called safety mode, you find the part that is fualty according to the number of blinks, you can find out what fualty part is cuasing the tv not to go on by downloading a service manual in pdf format or finding the blink codes, how many times does it blink count it carefully i may have a manual here and maybe can tell you what to replace.

Check BL_ERR pin on back light inverter board, what is volt reading that you get before and after tv shuts down? Let me know to proceed.

BTW, I really enjoyed your quote * I don't trust the blinking anymore *

I have a vizio tv model m50-c1. I have audio and backlight but nothing on screen. I have replaced the t conn board and did not fix the problem. Any idea on what my next step would be? thanks

1. Screen buffer test: Disconnect the two flex cable between the T-CON board & the screen one by one to see if one cable is disconnect the picture is come on a half a screen or not, if it does, the screen buffer board is bad that is not fixable, you need a new screen.
2. If the buffer test with no result, i will try a new main board.

If you have no picture and no sound, go with the main board first since that board works with both. If you have sound try the t con board first since it specializes in the video that appears on our screen..

Denon avr-3805 suddenly picture went out on tv (says no signal). Denon shows 'voff' on the screen. I cant figure out what happened.

I called customer support and they had not heard of this problem, and could not even tell me what the "V.Off" showing on the display represents. But, . . . the problem was solved by resetting the memory - by powering off, and powering back on while holding down both the Mode and Analog input buttons. Although this wiped out all my settings, the "V.Off" on the display disappeared, and the video now works. Problem solved.
